John I of Brabant

John I of Brabant (1254-3 May 1294) was the Duke of Brabant from 1267 to 1294, succeeding Henry IV of Brabant and preceding John II of Brabant.

Biography
John was born in 1254 in Leuven, the son of Henry III of Brabant and Adelaide of Burgundy. In 1267, his mentally-deficient brother Henry IV of Brabant was deposed in John's favor, and in 1288 John seized control of the Duchy of Limburg from the Electorate of Cologne after the Battle of Worringen, defeating the coalition of rival states despite having inferior numbers. On 3 May 1294, he was killed by Pierre de Bausner in a duel during marriage festivities in Bar-le-Duc, Lorraine, and his tomb was destroyed in 1566 by Protestant iconoclasts.
